Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural planting equipment technology, and in particular to a seed cultivation trough. Background Technology
[0002] Traditional seed trays or cultivation troughs have a fixed depth, making it difficult to meet the diverse needs of different seed species for substrate depth and root space during germination and seedling growth. Especially after germination, roots require more space to grow and more precise water control. A fixed, shallow trough can easily lead to root entanglement or restricted development, while a deep trough can cause over-soaking of seeds in the early stages. Furthermore, poor drainage can easily lead to root rot. Current technology lacks a cultivation trough that allows for convenient adjustment of planting depth and effective drainage management. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a seed cultivation trough, including a trough body, fixed columns, a drain outlet, a draining component, a layered trough, guide holes, a slider, a groove, and a locking block. The trough body is a square trough, and the fixed columns are vertically fixed at the four corners of the bottom inner wall of the trough body. The drain outlet is provided at the bottom of the trough body, and a draining component for controlling the opening and closing of the drain outlet is provided inside the drain outlet. The layered trough is movably installed inside the trough, and several rooting holes are evenly distributed at the bottom of the layered trough. The layered trough is a square trough, and the guide holes are provided at the four corners. Each guide hole corresponds to one of the four fixing posts, which are square posts. Each fixing post has a sliding groove on two opposite sides around its perimeter. The guide hole is square and has a slider that is slidably connected to the sliding groove at the corresponding position. The other two opposite sides around the fixing post have locking blocks evenly arranged vertically. The fixing post has a groove that matches the locking block at the corresponding position. One end of the locking block is fixed in the groove by a pin and the locking block can rotate along the pin.

[0023] The present invention will be further described in conjunction with the accompanying drawings and embodiments.
[0024] like Figures 1-6 As shown, the seed cultivation trough of this utility model includes a trough body 1, fixing posts 2, drainage outlets 3, drainage components 4, layered troughs 5, guide holes 6, sliders 7, grooves 8, and locking blocks 9. The trough body 1 is a square trough. The fixing posts 2 are vertically fixed at the four corners of the bottom inner wall of the trough body 1. The drainage outlet 3 is provided at the bottom of the trough body 1. The drainage component 4 is provided inside the drainage outlet 3 to control the opening and closing of the drainage outlet 3. The layered trough 5 is movably installed inside the trough body 1. Several rooting holes 51 are evenly distributed at the bottom of the layered trough 5. The layered trough 5 is a square trough and the guide holes 6 are provided at the four corners. The guide hole 6 is connected to the four fixed posts 2. The fixed posts 2 are square posts. Each fixed post 2 has a sliding groove 21 on two opposite sides around its perimeter. The guide hole 6 is a square hole and a slider 7 is provided at the position corresponding to the sliding groove 21 and is slidably connected to the sliding groove 21. The locking blocks 9 are evenly provided vertically on the other two opposite sides around the fixed posts 2. The fixed posts 2 have grooves 8 that match the locking blocks 9 at the positions corresponding to the locking blocks 9. One end of the locking block 9 is fixed in the groove 8 by a pin and the locking block 9 can rotate along the pin.
[0025] The drain outlet 3 is funnel-shaped and the lower part of the drain component 4 is adapted to the drain outlet 3. The upper part of the drain component 4 is provided with a first handle 41.
[0026] A sealing ring 42 is provided on the lower outer wall of the drain component 4. The outer edge of the sealing ring 42 contacts the inner wall of the drain port 3. A second handle 52 is provided on both sides of the layered groove 5. The slider 7 is a T-shaped block and the slide groove 21 is a T-shaped groove.
[0027] The tank 1 is a square tank with an open top. A funnel-shaped drain outlet 3, wider at the top and narrower at the bottom, is machined at the center of its bottom. A drain component 4, with its lower part matching the shape of the drain outlet 3, is inserted into the drain outlet 3 to control its opening and closing. An annular sealing ring 42 is embedded in the lower outer wall of the drain component 4. When the drain component 4 is fully inserted, the sealing ring 42 is pressed tightly against the inner wall of the drain outlet 3, forming a seal. A first handle 41 is fixed to the top of the drain component 4 for easy gripping to open and drain the water.
[0028] At each of the four corners of the bottom inner wall of the groove 1, a vertically upward fixing post 2 is welded. The cross-section of the fixing post 2 is square. On two opposite sides of the fixing post 2, a T-shaped groove 21 extending along its entire length is formed. On the other two opposite sides, a plurality of grooves 8 are evenly distributed vertically. A locking block 9 is hinged to each groove 8 by a transverse pin, and the locking block 9 can rotate around the pin within the groove 8.
[0029] The layered groove 5 is also a square groove, slightly smaller than the inner cavity of the groove body 1, and is placed inside the groove body 1. Multiple small rooting holes 51 are evenly drilled at the bottom of the layered groove 5 to allow plant roots to grow downwards. A second handle 52 is fixed to each of the two outer walls of the layered groove 5. A square guide hole 6 is made at each of the four corners of the layered groove 5. T-shaped sliders 7 are fixedly installed on the inner wall of the guide holes 6 at positions corresponding to the T-shaped grooves 21 of the fixing posts 2.
[0030] During installation, align the four guide holes 6 of the layered groove 5 with the four fixed posts 2 and insert it. At this time, the T-shaped slider 7 inside the guide holes 6 is precisely embedded in the T-shaped groove 21 of the fixed post 2. This allows the layered groove 5 to slide up and down along the fixed post 2, and it cannot rotate or move horizontally.
[0031] Height adjustment operation:
[0032] Unlock: Rotate the locking block 9 on the fixing post 2, which is in the current locked position (i.e., stuck below the bottom edge of the layered groove 5), by hand, so that it is completely retracted into the groove 8.
[0033] Lifting: The second handle 52 is used to lift or press down the layered groove 5, causing it to slide along the fixed column 2 to the desired target height. The T-shaped slider 7 slides within the T-shaped groove 21, ensuring smooth movement.
[0034] Locking: At the target height, rotate the locking block 9 on the fixing post 2, located below the bottom edge of the layered groove 5 (or immediately adjacent to the lower edge of the guide hole 6), so that it partially protrudes out of the groove 8. After releasing the layered groove 5, its bottom edge rests on the protruding locking block 9, thus being firmly supported and locked at that height.
[0035] Repeat: Depending on the plant growth stage (such as sowing period, germination period, seedling growth period), the above steps can be repeated to adjust the height of the layered trough 5.
[0036] Drainage Operation: When it is necessary to drain the liquid accumulated at the bottom of the tank 1 (such as excess nutrient solution or rainwater), simply lift the drain component 4 upwards using the first handle 41 to disengage the sealing ring 42 from the inner wall of the drain port 3, and the liquid will drain out from the drain port 3. After drainage is completed, reinsert the drain component 4 into the drain port 3 and tighten the sealing ring 42 to close the drain.
